arm64: dts: rockchip: Fix DMA for Indiedroid Nova Bluetooth

Browse Source 
When the device was first added, there was a problem with the bluetooth
controller that manifested when DMA was enabled for the underlying UART
interface. At some point in the intervening time the problem appears to
have been resolved. Add the UART rx and tx channels back to re-enable
UART.
